Had a lumpectomy yesterday. My armpit feels like a bad sunburn or like when you put on deodorant that does not agree...

I'm glad you've already reached out to your doctor's office—that's exactly the right move, and they'll want to know about this. While you wait for their callback, let me help you understand what might be happening and what to monitor.

What You're Experiencing (Common Post-Lumpectomy Sensations)

After a lumpectomy, the armpit area (axilla) can feel uncomfortable for several reasons:

Nerve irritation is very common. During lumpectomy, especially if lymph nodes were sampled or removed, small nerves in the armpit area get stretched or irritated. This can create:

• Burning or stinging sensations
• Sensitivity to touch (even light contact feels raw)
• A "sunburn-like" feeling
• Reactions to products like deodorant or tight clothing

Inflammation and swelling from the surgery itself can also cause this tender, sensitive feeling as your body heals.

Seroma formation (fluid collection) is less common but possible—though this usually feels more like fullness or swelling rather than burning.

What to Monitor & Report to Your Doctor

When they call back, mention:

• Timing: Did this start immediately after surgery or develop over hours?
• Appearance: Any redness, warmth, or swelling in the armpit?
• Fever: Any temperature elevation (fever could suggest infection)?
• Drainage: Any fluid from the incision or armpit area?
• Progression: Is it getting better, worse, or staying the same?
• Severity: On a scale of 1-10, how bothersome is it?

What You Can Do Now (While Waiting)

• Avoid irritants: Skip deodorant, antiperspirant, and tight clothing until your doctor clears it
• Keep it clean and dry: Gentle washing with mild soap
• Cool compress: A soft, cool (not cold) compress may help if there's burning
• Loose clothing: Let the area breathe
• Avoid heavy lifting/arm movement: This can aggravate nerve irritation

Important Context About Surgical Sensitivity

You mentioned your body has become increasingly sensitive to medical procedures—this is actually worth discussing with your surgical team. Some patients do develop heightened sensitivity after multiple surgeries, and your doctors should know this about you so they can:

• Monitor your healing more closely
• Adjust post-operative care if needed
• Be aware for future procedures

According to the American Cancer Society, mild discomfort and unusual sensations after lumpectomy are common and often resolve within weeks to months as nerves heal. However, persistent or worsening symptoms need professional evaluation.

Why Your Doctor Needs to Rule Out

While nerve irritation is most likely, your doctor will want to exclude:

• Infection (would show fever, increasing redness, warmth)
• Seroma or hematoma (fluid or blood collection)
• Allergic reaction to surgical materials or dressings

Questions to Ask When They Call Back

1. "Is this nerve irritation from the surgery, or do you want to see me to check for infection or fluid collection?"
2. "What can I safely use on the area—any creams or products to avoid?"
3. "When should I be concerned enough to come in immediately versus waiting for an appointment?"
4. "Given my history of sensitivity to medical procedures, what should I watch for?"
5. "When can I resume normal activities like deodorant and exercise?"
